All walkie talkie radios need batteries in just the
same way that mobile phones run on batteries. In most radio models the
batteries are rechargeable, but in other models they might be
replaceable batteries that cannot be recharged. Rechargeable batteries
are by far the cheaper option in the long term as the cost of
replaceable batteries can add up to a considerable amount over time.
have evolved considerably over the years. The extreme popularity of
mobile phones has no doubt accelerated the evolution of batteries to
smaller and more powerful units with a much longer active battery life.
This has been of obvious benefit to the walkie talkie radio market as
well, whether it is the more traditional analogue radios or the more
modern digital radios.
Rechargeable batteries have two main
factors that you need to consider: run time and life cycle. The run time
of a battery is the length of time a fully charged battery will last
before its charge runs out under normal, or average, conditions. The
life cycle of a battery is the number of times a battery can be
recharged before it will no longer hold a charge, and therefore needs to
be replaced with a new battery.
There are other factors to
consider, such as the amp-hour rating and the voltage of the battery. If
you want a long lasting battery, go for a high amp-hour rating. The
volts that a battery is rated at determines its power output; the higher
the volts, the greater the power output. This rating is not really too
important when it comes to walkie talkie radios, but definitely comes
into its own with power tools, for example.
rechargeable batteries used in walkie talkie radios are the nickel-metal
hydride battery (NiMH), the nickel-cadmium (NiCad) battery, and the
lithium-ion (Li-Ion) battery. The NiMH and NiCad batteries are similar
to each other in many ways. The NiMH battery weighs less and has a
capacity two to three times that of a NiCad battery of similar size.
However, the NiMH battery has a shorter run time and fewer life cycles
than the NiCad battery, and it doesn't perform very well in low
The Li-ion battery is a relative newcomer. It
has a good energy-to-weight ratio and no memory effect, something that
both the NiMH and NiCad batteries suffer from. The Li-ion also has a
relatively fast recharge time and increased life cycles over the other
two battery types. All rechargeable batteries lose charge when not in
use, but the Li-ion exhibits a slower charge loss than the others.
a good battery is worth getting for its long life and charge-holding
abilities, it won't increase the sound quality, or any other of the
walkie talkie's features. It is simply a power source that allows the
radio to function properly. This applies to new or used radios, leisure
radios or business radios, or even analogue or digital radios. It is
always a good idea to get the best quality battery you can for your
walkie talkie radios, and only replace it when it stops functioning
